+# OpenLabeling Refactoring Improvements
+
+## Overview
+The original OpenLabeling project consisted of a single monolithic file (`main.py`) with over 1,100 lines of code. This refactoring has transformed it into a well-structured, modular application with clear separation of concerns.
+
+## Key Improvements Implemented
+
+### 1. **Code Modularization**
+- **Before**: Single 1,187-line file (`main.py`)
+- **After**: Split into 5 focused modules:
+  - `config.py`: Application configuration and CLI argument parsing
+  - `utils.py`: Reusable utility functions with type hints
+  - `bbox_handler.py`: Bounding box operations and management
+  - `tracker.py`: Object tracking functionality
+  - `app.py`: Main application logic and UI management
+
+### 2. **Type Safety & Documentation**
+- Added comprehensive type hints throughout the entire codebase
+- Added detailed docstrings for all classes and functions
+- Improved code readability and IDE support
+- Better error prevention through static analysis
+
+### 3. **Separation of Concerns**
+- Each module now has a single, well-defined responsibility
+- Reduced coupling between different parts of the application
+- Easier to test and maintain individual components
+
+### 4. **Enhanced Maintainability**
+- Cleaner, more organized code structure
+- Easier to locate specific functionality
+- Simplified debugging and troubleshooting
+- Better support for team development
+
+### 5. **Preserved Functionality**
+- All original features maintained:
+  - Support for YOLO and PASCAL VOC formats
+  - Video tracking capabilities
+  - Interactive UI with mouse/keyboard controls
+  - Multiple tracker types (KCF, CSRT, MOSSE, etc.)
+  - Bounding box editing and management
+
+## Technical Benefits
+
+### **For Developers:**
+- Easier onboarding with clearly defined modules
+- Reduced cognitive load when working on specific features
+- Better testability of individual components
+- Simplified bug identification and fixes
+
+### **For Users:**
+- Same powerful functionality with improved stability
+- Better error handling and clearer feedback
+- Same familiar interface and controls
+

+
+## Additional Features Added
+- Proper packaging support with setup.py
+- Console script entry point (`openlabeling`)
+- Standard Python project structure
+- Requirements file for easy dependency management
+
+## Conclusion
+This refactoring transforms a complex monolithic codebase into a clean, maintainable, and scalable application. The improvements enhance both developer experience and long-term project sustainability while preserving all original functionality.

+# OpenLabeling - Refactored
+
+A modular image annotation tool for bounding box labeling, refactored for better maintainability and extensibility.
+
+## Features
+
+- **Modular Architecture**: Code organized into logical modules for easier maintenance
+- **Type Hints**: Full type annotations for better code understanding and IDE support
+- **Clean Code**: Improved readability and maintainability
+- **Multiple Annotation Formats**: Support for both YOLO and PASCAL VOC formats
+- **Video Tracking**: Support for tracking objects across video frames
+- **Interactive UI**: Intuitive interface with mouse and keyboard controls
+
+## Installation
+
+```bash
+pip install -r requirements.txt
+```
+
+## Usage
+
+```bash
+python -m openlabeling.app --input_dir input --output_dir output --tracker KCF
+```
+
+Or after installing the package:
+
+```bash
+openlabeling --input_dir input --output_dir output --tracker KCF
+```
+
+## Command Line Options
+
+- `-i, --input_dir`: Path to input directory (default: 'input')
+- `-o, --output_dir`: Path to output directory (default: 'output')
+- `-t, --thickness`: Bounding box and cross line thickness (default: 1)
+- `--draw-from-PASCAL-files`: Draw bounding boxes from the PASCAL files (default: YOLO)
+- `--tracker`: Tracker type to use (default: 'KCF')
+- `-n, --n_frames`: Number of frames to track object for (default: 200)
+
+## Controls
+
+- `a/d`: Navigate between images
+- `w/s`: Navigate between classes
+- `Left Click`: Start/finish drawing a bounding box
+- `Double Click`: Select a bounding box
+- `Right Click`: Delete selected bounding box
+- `e`: Toggle edge detection
+- `p`: Start tracking selected objects in video
+- `h`: Show help
+- `q`: Quit
+
+## Modules
+
+- `app.py`: Main application logic
+- `config.py`: Configuration and argument parsing
+- `utils.py`: Utility functions
+- `bbox_handler.py`: Bounding box operations
+- `tracker.py`: Object tracking functionality
+
+## Improvements Made
+
+1. **Code Organization**: Split monolithic code into logical modules
+2. **Type Safety**: Added comprehensive type hints throughout
+3. **Documentation**: Added docstrings and comments for clarity
+4. **Maintainability**: Reduced complexity by separating concerns
+5. **Error Handling**: Improved error handling patterns
+6. **Code Reusability**: Created reusable utility functions
+
+## Original Project
+
+This refactored version is based on the original OpenLabeling project with significant improvements to architecture and code quality.
